Two-assets portfolio with trapezoidal oriented fuzzy present values

Anna Łyczkowska-Hanćkowiak , Krzysztof Piasecki


The main goal of thispaper is to present characteristics of a two-asset portfolio for thecase when composing securities areevaluated by imprecise present valuesmodelled by an orderedtrapezoidal fuzzy number. The future value is determinedas random variable under the Gaussian distribution of probability. The expected discount factor is defined for the caseof simple return rate. Obtained model is an extension of the Markowitz theory to thecase of securities present values given by ordered fuzzy numbers. Throughout the analysis a fuzzy expected discount factor and imprecision risk assessments are calculated. Thanks to that,there arises a possibility to describe the impactof portfolio diversification on imprecision risk. Presented theoretical resultsare supported by numerical example
